Denture Replacement Clinical Case in Melbourne

Can New Dentures Replace Old, Discoloured and Loose Dentures in Melbourne?

Case Note ID: Dec-2024-UDR

Location: Dental House Group (serving Melbourne’s north and west)

Primary Treatments: Complete Upper Denture Replacement

Supporting Technology: Denture Fabrication Systems, Impression Materials, Bite Registration

Presenting Clinical Problem

A patient presented with multiple concerns regarding existing upper denture requiring complete replacement. The clinical presentation included significant denture discolouration despite regular cleaning affecting appearance, loose denture fit compromising retention and stability during speaking and eating, visible denture wear with chipping affecting structural integrity, and functional difficulties with speech clarity due to poor denture stability.

The primary clinical objectives were to fabricate new upper denture with improved aesthetics and colour stability, restore appropriate denture retention and stability for improved function, address structural concerns through complete denture replacement, and improve speech clarity through proper denture fit and positioning. Treatment planning involved comprehensive assessment of ridge anatomy and functional requirements.

Treatment Plan & Clinical Process

Phase 1: Assessment and Planning

• Complete oral examination and assessment of existing denture
• Evaluation of ridge anatomy and tissue health
• Assessment of vertical dimension and bite relationships
• Discussion of denture design options and aesthetic preferences
• Treatment timeline and appointment scheduling

Phase 2: Impression and Fabrication Procedures

• Primary impressions for initial model fabrication
• Custom tray fabrication for final impressions
• Final impressions capturing detailed ridge anatomy
• Bite registration to establish proper jaw relationships
• Tooth selection for shade, size and shape

Phase 3: Try-In and Final Denture Delivery
 

• Wax try-in appointment to verify tooth position and aesthetics
• Adjustments to tooth arrangement and bite relationships
• Laboratory processing of final denture
• Denture delivery with fit verification and adjustments
• Post-insertion care instructions and follow-up scheduling

Clinical Outcome

Treatment was completed over approximately two months with six appointments. A new complete upper denture was fabricated to replace the old, discoloured and loose denture. The new denture improved retention, stability and appearance.

Individual results vary. Denture adaptation requires time and patience. New dentures may initially affect speech and eating until adaptation occurs. Ridge resorption continues over time causing dentures to become loose and require periodic relines or replacement. Denture longevity depends on oral hygiene, tissue changes and maintenance. Some patients require multiple adjustment appointments. No guarantees can be made about outcomes.

Frequently Asked Questions for Melbourne Patients

Why do dentures become discoloured over time?
 
Denture discolouration results from staining substances (coffee, tea, tobacco), plaque accumulation and acrylic material degradation. Some discolouration is intrinsic to aged acrylic and cannot be removed through cleaning. Regular professional cleaning slows but does not prevent this process. Eventually replacement becomes necessary.

How often should dentures be replaced?
 
Denture longevity typically ranges from 5-10 years before replacement becomes necessary. Factors affecting lifespan include ridge resorption, tooth wear, acrylic degradation and patient care habits. Loose dentures accelerate ridge loss and should be evaluated promptly rather than waiting for scheduled replacement.

Why do dentures become loose over time?
 
Denture looseness results primarily from ongoing ridge resorption, a normal process following tooth loss. As the ridge changes shape, dentures no longer fit properly. Weight loss, medications and health conditions can accelerate ridge changes. Periodic relines restore fit, though eventual replacement is typically required.
